Citibank Private Banking is also available to those who Citi forecasts are likely to become eligible for the Private Banking. They are quite aggressive about talking to young lawyers and getting them pulled into the Citi family.
I have several friends who use their services.
That said, they probably see only a small fraction of the full Private Banking suite of services/courtesies, but I've certainly seen reports, paperwork that they've received saying "Private Banking."
